The one thing I can tell you about DOM manipulation techniques within JAWS
scripts is that JAWS absolutely hates chaining the object methods more than one
layer deep. In a number of instances, I've found that while the chain is
conceptually sound, the function only works if I walked the individual calls
into variables. Example from below, "oFrame.document.body.innerText" is a
valid call in JavaScript, but in JAWS script you may find it only works if you
do it like this:
let oDOM = ieGetCurrentDocument ()
let oFrame = oDOM.frames(2)
let oObject = oFrame.document
let oObject = oObject.body
let sText = oObject.innerText

I have no idea what the difference is but I
have always used
IeGetCurrentDocument when
playing with the DOM.
I would try something
like the following:
String
Function GetFrameContents ()
Var
Object oDOM,
Object oFrame,
String sFrameText
Let oDOM =
ieGetCurrentDocuemnt ()
Let oFrame =
oDOM.frames(2)
Let sFrameText =
oFrame.document.body.innerText
Return sFrameText
EndFunction
You may need to fiddle with the document.body.
and the innerText to maybe
innerHTML or
outerText dependant on what sort of output you need.
You also need to take into account the origin
of the frame contents. To
increase security
modern browsers prevent scripts from running from a
different domain. If the frame contents are
from http://siteA.com and the
main page is http://siteB.com
you wont be able to access it.
Hope this helps.

Subject: [jawsscripts] Problem capturing text
using DOM in IE 11
I'm
having a problem capturing text from an HTML frame using the
DOM in IE
11. This is Windows 7 and Jaws
15.
The following code works with IE8 and
Jaws 13 but not with IE 11 and Jaws
15:
String Function WorkAreaText ()
var
object doc,
object
TopWindow,
object win,
object frames,
string
sBuffer
Let doc =
ie4GetCurrentDocument ()
Let topWindow = doc.parentWindow
Let topWindow
= topWindow.top
Let frames = TopWindow.frames
Let win =
ieGetUnrestrictedWindow(frames(2)).document.body
Let sBuffer =
win.createTextRange().text
return sBuffer ;the text in the frame
EndFunction
I'd
appreciate any suggestions.
Also can anyone explain the difference between
ie4GetCurrentDocument ()and
ieGetCurrentDocument ().
Although I've successfully used the
function ieGetUnrestrictedWindow() many
times in the manner shown above I've never
seen a good explanation of it.
Can anyone
explain it?
